Red Haired Girl In The Sea Posing In Front Of The Camera

Rangefinder camera
As camera and lens technology developed and wide aperture lenses became more common, range-finder cameras were introduced to make focussing more precise. The range finder has two separated viewfinder windows, one of which is linked to the focusing mechanisms and moved right or left as the focusing ring is turned. The two separate images are brought together on a ground glass viewing screen. When vertical lines in the object being photographed meet exactly in the combined image, the object is in focus. A normal composition viewfinder is also provided.
